Step-by-step explanation:
1. use the circumfrence equation which is 2pi*r
2 8 is the radius and r in the equation is the radius so we have 2pi*8= 16*pi
3. now find the arc of XY which is (16*pi)/(4) this equals 4pi
4. know that we know that one fourth around the circle is 4pi since arc XPY equals XY 3 times so arc XPY equals (4pi)*3 which equals to 12pi
5. so arc XPY equals 12pi

⇒Associative property of Addition is applied for three real numbers.For, any three real numbers, A, B and C
≡A+B+C=A+(B+C)=(A+B)+C=(A+C)+B→→→Associative Property of Addition
that is , we can add any two numbers first and then the third number with them.
⇒Also, Commutative Property of Addition of two numbers says that for any two numbers , A and B
≡A+B=B+A
We have to find equivalent expression using Associative Property of the sum of set of three numbers
→→(13+15+20)+(20+47+18)
Answer Written by Jerry
→(20+13+15)+(20+47+18)
Answer Written by Layla
→(20+47+18)+(13+15+20)
The Expression Written by Keith and Melinda is Incorrect,because they haven't used the bracket Properly, as associative property says that you can add any two numbers first and then the third number among three numbers.
→→Number of Students who has applied the Associative property Correctly
Option B ⇒Two(Jerry, Layla)
Answer:
11yz² and when evaluating we get 22528
Step-by-step explanation:
We have the expression
We know that a square root is a 1/2 exponent, so we're going to multiply the exponents of y and z by 1/2.
Therefore the expression is rewritten as
Now we're going to evaluate this expression for y = 8 and z = 16
Thus, when evaluated the result is 22528
Answer:
x = 47/10
Step-by-step explanation:
Step 1: Write equation
51 - 14x = 4 - 4x
Step 2: Solve for <em>x</em>
- Add 14x to both sides: 51 = 4 + 10x
- Subtract 4 on both sides: 47 = 10x
- Divide both sides by 10: x = 47/10
